"HYDRooARBoN-BURNER.

lTo aZZ whom z'zmay concern:

Be itknownthat I, ROBERT Gr. SPEER, a citi- `Zen of theUnited States,residing at St. .Louis, Missouri, have invented certain new `and usefulImprovements in Hydrocarbon Burners, of which the following is a full,clear, and exact description, reference being had to the yaccompanyingdrawings, formingaparthereof. v M

My invention relates to new and useful improvementsin hydro-carbonburners, the

lprincipal objectl of my invention being to provide a comparativelysimple, `inexpensive device in which liquid hydro-carbon can be burnedto produce, without smoke `and odor, a comparatively high degree ofheat, said device being particularly intended for use for cooking andheating purposes. With the above and other objects in View, my inventionconsists in certain novel features of construction and arrangement ofparts hereinafter more fully described `an claimed. i

Figure 1 isa planview of a burner of my improved construction. Fig. 2 isa vertical section taken` approximately on the line 2-2 of Fig. 1. Fig.3 is a cross space section taken approximately on the line 3-3 of Fig.1.

Referring by numerals to the accompanying drawings,10 designates thebase of my improved burner, which is in the form of an open top box, theend walls of which are slightly higher than the side walls, and locatedin one end of this box-like base is a hollow casing 11, which providesan expansion chamber 12, the same'extending entirely across the base.Leading into one end of this `chamber is the liquid hydro-carbon supplypipe 13, the same being connected to a suitable gravity or pressuresupply tank. The upper portion of theburner comprises a plate 14, whichis4 substantially narrower `in width than the base 10,-l and extending`Specification. of Letters Patent.

formed integral `with` said plate `near its :ends are downwardlyprojecting tubular lugs 19. Formed integral with the plate 14 ,adjacentto the lugs 19 are upwardly projecting `brackets 20, upon which rests ahoriare closed in any` suitable manner preferably by means of caps.underside of this tube 21 immediately `above the central portions of thetubular lugs 19 are jet nozzles 22. Connected to and leading downwardfrom the central portion of tube 21 through the tubular lug 18 is a tube28, the same being bent to form a coil 24 in the lower portion of thebase 10 and the opposite end of this tube is tapped into the housing 11at the opposite end of the chamber 12from the supply pipe 13.

To start my improved burner, a small amountof liquid hydro-carbon isplaced in the boxlike base 10, and upon ignition, the tube 23, housing11, and the upper portion of l the burner become heated. Liquidhydro-carbon enters the expansion chamber 12 through pipe 13, and thegreater portion of thisk liquid hydrocarbon is vaporizedwithin thechamber 12. This vapor, together with a small percentage of the liquidhydro-carbon passes through tube 23, in which all of the hydro-carbon isvaporized and the resulting vapor passesinto tube 21, and dischargesfrom thence through the jet nozzles 22 downward through `the tubularlugs 19. This action draws air downward through said tubular lugs, whichair is mixed with the vaporized' hydrocarbon and the resulting mixturedischarges beneath the curved lower edges of walls l5 and upon beingignited this vapor burns with a high degree of heat and without odor.`During the continued operation of the burner, lthe combustion of thevaporized liquid hydrocarbon maintains the burner in a heated condition,so that the supply of liquid hydro-carbon delivered to `the lexpansion,

chamber 12 is all vaporized therein. The expansion chamber 12 permitsthe liquid hydro-carbon to expand as it is vaporized, and thus the flowof vapor or gas from the jet nozzles 22 is even and without pulsations.

A burner ofv my improved construction is particularly designed to usekerosene or coal-oil,as fuel, although any form of liquid hydro-carboncan be advantageously and economically burned in the device.

Tapped into the zontally disposed tube 21, the ends of which A *l Copiesof this patent inay be obtained for ItY be readily understood 'thatAminorV changes in the size, form and construction of the various partsof my improved burner may be made and substituted for those herein shownand described, Without departing from the vspirit olify myinvention, thescope or" which is setv forth in the appended claim.

I claim: In a burner of the v.class described, a base provided in one'end With an 'expansion' vided With a pair of openings, perforated lugs.integral With plate, iand `which lugs vdepend from said plate around the-openings therein, aburner tube positioned above saidplate,jetno'zzlesseated `in the' underside of said burner, tube directly above.the openings-in the plate, apipe.v leading from the expansion'chamberto theburner tube, and means' yfor delivering .hydro-carbon to theexpansion chamber. i y
